SHEET-METAL PANELING FOR CEILINGS, 86C- SPEGIFICATION forming part of Letters Patent No. 52 4,932, dated August 21, 1894.

Application filed March 31, 1894..

To all whom it may concern:

Beitknown that I, FRANK G. CALDWELL,

a cltlzen of the United States, residing at Wheeling, in the county of Ohio and State of West Virginia, have invented new and useful Improvements in Sheet-Metal Paneling for Ceilings, &c., of which the following is a specification. This invention relates to sheet metal ceilings, walls, and the like, wherein .a series of sheet metal panels and moldings are so assembled and applied as to provide a continuous metallic surface which can be painted, or otherwise decorated or ornamented in any pattern or manner desired for the purpose of presenting a handsome appearance.

In constructing a ceiling or wall ofthe type alluded to it is very desirable and advantageous to adjust the panels relatively to one another to secure accurate and nice joints and perfect work at comparatively small expense; and it is also desirable in assembling the panels to have them, in a measure interlocked, so that when adjusted to the correct position they will not shift or become disarranged or displaced prior to rigidly nailing or otherwise fastening them to the joist, studding, or wooden, or other foundation. To accomplish this by novel, simple, efiicient and economical means is the chief object of my present invention; and to that endit consists essentially in a sheet metal panel having at one edge portion a plurality of parallel corrugations or flutes, and the opposite edge portion formed integral with an arched molding gated or fluted, and adapted to adj ustably fit the corrugated edge portion of another panel.

The invention is illustrated by the accom panying drawings, in which- V Figure 1: is a sectional view taken through two panels which are constructed and assembled in accordance with my invention; and Fig. 2 is a detail plan View of one of the panels.

In order to enable those skilled in the art to make and use my invention,I will now describe the same in detail, referring to the drawings, wherein- The numeral 1 indicates the body portion of a sheet metal panel of the type designed for ceilings, walls, and the like, in order to decorated or ornamented to present the desired handsome appearance.

The body portion of the panel may be struck up, or constructed otherwise to suit the conditions required, and this panel is provided at one edge portion with a plurality or lambdoidal or V-shaped corrugations or flutes 2, of comparatively small dimensions. opposite edge portion of the panel is formed integral with an ornamental arched molding 3 of any desired or suitable shape in crosssection. The molding is provided along one side with a plurality of lambdoidal or V- shaped corrugations or flutes 4., and along the opposite sides with a flange-like portion which isalso corrugated or fluted, as at 5, the same as or similar to the flutes or corrugations 2 and 4.

The corrugations formed and arranged in the manner above described not only impart rigidity to the sheet metal panel and render itstronger and more durable, but they fulfill the conditions required to adj ustably assemble the plates and practicably interlock them prior to rigidly nailing or fastening the same to the joist,- studding, or wooden or other foundation 6.

In constructing a ceiling according to my invention, the corrugated or fluted flangelike portion 5 of the molding 3 is designed to engage and interlock with the corrugated or fluted edge portion of another panel, as will be understood by reference to Fig. 1. It will be obvious that the corrugated or fluted portions 2 and 5 can be adjusted one upon the other in order to vary the distance between two ornamental arched moldings 3; and that when the desired adjustment hasbeen effected, the interlocking of the corrugations or flutes renders it impossible for the panels to shift or become disarranged or displaced prior to rigidly fastening the panels to the joist, studding, or other foundation. In attaching the panels I preferablydrive nails through the overlapping corrugated or fluted portions 2 and 5, as illustrated in Fig. 1.

The sheet metal panel is also provided along the edge or ends which lie at right angles to the corrugated and fluted edge portion 2, with a plurality of lambdoidal or V- The H shaped" corrugations .or flutes 7, which run.

continuously :from the corrugations or flutes 2 to the corruga-tionsor flutes 4, thereby stiff-= ening and strengthening the panel, and enabling other panels to be adjustably fitted thereto in the same manner as the corrugated or fluted portions 2 and 5 are adj ustably fitted together.

By the means described, it is possible to accurately fit the panels together and adjust them relatively to one another to secure accurate and nice joints and the correct position of the parts; and, furthermore, the i'nterlocking of the fluted or corrugated portions renders it impossible for the panels to shift or become disarranged or displaced prior to rigidly securing them by nails orother'jfastening devices. I am thus enabled to materially economize in the construction of a ceil-,

ing or wall, while obtaining perfect work;

Whereas tosecure a desirable finish very .ex-

tensive design-s have heretofore been essential.

My invention enables a ceiling of sheet metal to be constructed that combines cheapness with perfect work, while separate or in-' dependent moldings are avoided, the cost of manufacture is lessened, the required finish is obtained at .,a.sma1l expense, a perfect and nicely fitting lap joint .is obtained, and the panels are adjustable ,as regards Width and length. The corrugated fluted or crimped portion -7 is advantageous in producing perfect laps without buckling, and secures the adjustment as to length. The corrugations,

crimps or flutes alsoform alpine of panel work susceptible of beingdecorated in any manner desired.

The formation-of the arched molding intgegral with the sheet metal panel secures the desired finish and imparts t0 the sheets that rigidity necessary in work of this kind. The style :or patternof thearched molding issusceptible of any change to meet the require. ments of the trade.

The sheet metal panels are constructedot considerable length as compared .to their width; but, obviously, they maybe of' any required ornecessary size. 7

Having thus described my invention, what I claim isl. A sheet metal panel having one edge portion providedwi-thaplurality of corrugations or flutes, and the opposite edge portion formed integral with an arched molding having a corrugated or fluted flange extension adapted to adjustably fit the corrugated edge portion of another panel, substantially as described.

2. Asheet metal panel having oneedge portion formed integral with an ornamental arched molding, the opposite edge portion having corrugationsrunning parallel withthe median line of the molding, andanother edge portion having corrugations runningat right angles to the molding,substantially.as deries of contiguous sheet metal panels having one edge portion longitudinallycorrugated, and the opposite edge portions {formed inte- 'gral with "arched moldings from which vextend flange pOrtiQnshaving flambdoidalor'vshaped corrugations or flutes running parallel with the moldings, substantially as described.

jIn testimony whereof I have hereunto set -my hand and-afiixed my seal in presence .of two subscribing witnesses.
